A school has 400 students. They all come to school by bus, and each bus carries the same number of students. How many students might there be on each bus?
I put some counters into groups with the same number in each group. I can’t remember what I did, but I do remember that I had 12 counters. What might the groups have been?
Answer:
23 times 8 then divide the answer by two
(i looked it up and the answers are the same.)
Question 1 A. Do 23 times 2 times 2. This will give you the same answer as if you were to use 4.
Question 1 B. Use 10 times 2 plus the number in the ones place, then multiply them together.
Question 2. There would be an average of 40 student per bus, therefore, there will be 10 buses, and 40 students in each bus.
Question 3. You could put 12 counters in: 6 groups of 2, 2 groups of 6, 4 groups of 3, or 3 groups of 4. (I think there's more but that's all I can think of. Hope you got the memo)
Hope this helped! :D

Katie's mom gave her $20.00 to buy school supplies. Katie needs to buy 3 binders and some mechanical pencils. If each binder costs $3.25 and each mechanical pencil costs $1.50, how many mechanical pencils can Katie buy using only the money her mom gave her?
Answer:
6 pencils
Step-by-step explanation:
i looked it up
Answer:
6 Mechanical Pencils
Step-by-step explanation:
So Katie NEEDS 3 binders so that is given. 3.25 times 3 is 9.75 so subtract that from 20 which is 10.25. Divide 10.25 by 1.5 and get 6.8. You cant buy .8 of a pencil so you go down to 6.
How many four-digit whole numbers contain the digit pair "17" without other intervening digits? (Note that 2017 is one such example but 2107 is not.)
Answer: There are 209 4-digit nu numbers with 17 as consecutive digits
Step-by-step explanation:
17xx xx represent 00 through 99, a set of {100} members.
y17z. y can be 1 through 9 {9}. z can be 0 thru 9 {10}
ww17 which includes 10 thru 99, a set of {90}
Add 100+90+10+9 to get 209 possible combinations.

Use the graph representing bacteria decay to estimate the domain of the function and solve for the average rate of change across the domain.
0 ≤ y ≤ 80, −0.6875
0 ≤ y ≤ 80, −1.45
0 ≤ x ≤ 55, −1.45
0 ≤ x ≤ 55, −0.6875
The domain of the given function is [0,55] and the average rate of change is -1.45 so option (C) is correct.
What is the range and domain of a function?A function's range is the set of all values that the function accepts, and its domain is the set of all values for which the function is defined.
The domain is for the independent variable while the range is for the dependent variable.
The domain of a function is the set of input values that the function defines.
The function goes from x = 0 to x = 55 thus 0 ≤ x ≤ 55 will be the domain.
The average slope for (0,80) and (55,0)
⇒ (0 - 80)/(55 - 0) = -1.45
Hence "The domain of the given function is [0,55] and the average rate of change is -1.45".

4(b+1) ≤ 2(2b+1)+1
Is this equation no solution?
Very important
Answer:
it does not have a solution
Step-by-step explanation:
4(b + 1) ≤ 2(2b + 1)+1
4b + 4 ≤ 4b + 2 + 1
0 ≤ -1
0 isn't less than or equal to -1

Hey there!
Let's write this as a ratio/proportion.
The sum of this basic ratio is 4.25.
To figure out how much of each we have for 34, we divide this 34 by 4.25, our sum of the two ingredients. This will give us a factor we can multiply our two ingredient measurements by.
34/4.25=8
Now, we multiply our two ingredients by eight.
2.75(8)=22
1.5(8)=12
Note that these two add up to make 34 tablespoons.
Therefore, we have...
22 tablespoons of olive oil and 12 tablespoons of balsamic vinegar were used in the 34 tablespoons of bread dip.
I hope this helps! Have a great day! :)
